Vulnerability

Philips lists Holter SW, ST80i and Focal Point under Windows CLFS zero-day CVE-2022-37969

MedDevice Cyber Staff · Oct 20 · 2 min read · Via Philips product security advisories, 2022 archive

Philips listed three products on October 20, 2022, as related to CVE-2022-37969, a zero-day elevation of privilege flaw in the Windows Common Log File System Driver: Focal Point, Holter SW and the ST80i.

Microsoft states that an attacker who successfully exploited this vulnerability could gain SYSTEM privileges. An elevation of privilege bug needs code already running on the host, so it serves as the second stage of an intrusion.

On a Holter review station, that means the distance between a phishing click and full control of the box is one unpatched driver.

The flaw is in the OS inside the controller, or a system past end of service still in the field. As the maker, own the embedded OS and server lifecycle as a safety obligation, design controllers to update in the field, and make every fault degrade to a defined safe state.

Own the OS lifecycle. Patch the OS and server components on a schedule with a tested delivery path.
Design for field update. And for planned replacement, so an unpatchable unit has a path off the network.
Degrade to safe. A fault drives a defined safe state, never an unexpected stop on a life-sustaining device.
